ShopperPress 7.1.4 bug?

I think I’ve found a bug in 7.1.4. I’m using WP 3.8.1, PHP 5.3.13 and MySQL 5.1.62

When I create a product in a category and that product begins with a number rather than an alpha character, I always get 404 on the page.

If I re-create the product and start the name with an alpha character, it works fine.

I’m using permalinks, and the .htaccess, which is writable, is the standard one as follows:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Help appreciated!

Cheers, Laurie.
